Versuchsvorschrift

Benzeneacetamide (3.0 g, 0.022 mol) was dissolved in dichloromethane (60 mL) and N-bromosuccinimide (4.0 g, 0.022 mol) was added. The reaction was stirred at room temperature under UV light for 24 hr. The mixture was poured into water and the layers were separated. The organic layer was washed with water (2×50 mL) then with brine (1×50 mL). The organic layer was dried (magnesium sulfate) then chromatographed on silica (40% ethyl acetate/hexanes) to give 2-Bromo-2-phenylacetamide, compound h Rf 0.37, 40% ethyl acetate/hexanes; MS m/z 216 (M+H).
